Product description: D30V30F5 - step-down converter - 5 V 3.4 A - Pololu 4892

The D30V30F5 step-down converter from Pololu converts an input voltage in the range of 5 V to 45 V into a stable output voltage of 5 V. The module can deliver a continuous output current of up to 3.4 A , with typical efficiency ranging from 80% to 95% , depending on the input voltage and load. Thanks to the switching mode converter (SMPS) technology, this regulator is much more effective than traditional linear regulators, especially with large differences between the input and output voltage. The D30V30F5 has built-in protection against reverse polarity up to 40 V, input undervoltage, overcurrent and short circuit, as well as a thermal shutdown function. Additionally, the module is equipped with a soft start function that limits the starting current and gradually increases the output voltage. Thanks to its compact dimensions (17.8 x 20.3 x 9 mm) and the pinout system compatible with breadboards, the controller is easy to integrate into various projects.

D30V30F5 converter pins

  • VOUT - output voltage 5 V
  • GND - system ground
  • VIN - input voltage from 5 V to 45 V
  • EN - allows you to control the regulator's operation by setting it to low or high
  • PG - "Power Good" open-drain pin. Goes low when the regulator output voltage increases more than 7.5% above or drops more than 9% below the nominal voltage (with hysteresis). If this pin is used, a pull-up resistor must be connected.

The converter can be plugged directly into the breadboard , connected via wires or soldered into a dedicated printed circuit board.

Maximum continuous output current

The maximum output current achieved by the converter depends on the input voltage , as well as other factors such as ambient temperature, air flow and heat absorption. The graph shows the maximum output currents that the controller can deliver continuously at room temperature, without air flow and additional heat dissipation.

Efficiency of the converter system

Efficiency is defined as the ratio of output power to input power (Power out) / (Power in). It is one of the most important parameters of the converter, especially when working with portable energy sources. The D30V30F9 provides typical efficiencies ranging from 80% to 95% , depending on input voltage and load. Thanks to this, you can be sure that the converter operates with the highest possible efficiency, which translates into longer battery life or less heat generation in the system.
